Electrical safety and Electro-Magnetic Compatibility for this product is covered by the compliance with the EN/IEC Standard “Automatic electrical controls for household and similar use”:

• EN/IEC 60730-1 (general)
• EN/IEC 60730-2-9 (thermostat)

Safety Instructions

Make sure the mains supply to the thermostat is turned off before installation.

Important: When the thermostat is used to control a floor heating element in connection with a wooden floor or similar material, always use a floor sensor and never set the maximum floor temperature to more than 35°C.

Please also note the following:

• The installation of the thermostat must be done by an authorized and qualified installer according to local regulations.
• The thermostat must be connected to a power supply via an all-pole disconnection switch.
• Always connect the thermostat to continuous power supply.
• Do not expose the thermostat to moisture, water, dust, and excessive heat.

Mounting Instructions

Please observe the following placement guidelines:

• Place the thermostat at a suitable height on the wall (typically 80-170cm.).
• The thermostat should not be placed in wet rooms. Place it in an adjacent room and use floor sensor only. Always place the thermostat according to local regulation on IP classes and use floor sensor only.
• Do not place the thermostat on the inner side of an exterior wall.
• Always install the thermostat at least 50 cm. from windows and doors.
• Do not place the thermostat in a way that it will be exposed to direct sunlight.

Note: A floor sensor enables a more accurate temperature control and is recommended in all floor heating applications and mandatory under wooden floors to reduce the risk of over-heating the floor.

• Place the floor sensor in a conduit in an appropriate place where it is not exposed to sunlight or draft from door openings.
• Equally distant and >2cm from two heating cables.
• The conduit should be flush with the floor surface – countersink the conduit if necessary.
• Route the conduit to the connection box.
• The bending radius of the conduit must be min 50mm.

Connect the thermostat according to the connection diagram.

The screen of the heating cable must be connected to the earth conductor of the power supply cable by using a separate connector.

Note: Always install the floor sensor in a conduit in the floor.

• It will be possible to use only a room sensor. However, this option is not recommendable due to an increased risk of overheating the floor. See 4.9 Change to Room control only
• P03 appears on the relevant temperature control mode. See 4.10 Extending Maximum floor temperature limitations to 45°C

Advanced Programmable Timer

The Advanced Programmable Timer mode enables the set-ting of a timer- controlled program for automatic comfort temperature, and an energy-saving lower setback tempera-ture if standard room comfort temperature is not required. The function consists of 2 programs:

• P1 with 4 events in 5 days (Mon. Tue. Wed. Thu. Fri.)
• P2 with 4 events in 2 days (Sat. Sun.).
  P1: Press   and hold to display Mo. Tu. We. Th. Fr.

P1, Event 1:

1. Use < or > to select the start time.

2. Press  to accept the setting.

3. Use < or > to select the temperature.

4. Press  to accept the setting.

P1, Event 2-4:

Repeat the Event 1 procedure for programming Event 2-4.

| P2: Sa. Su. are now shown in the display.

P2, Event 1:

2. Press  to accept the setting.

3. Use < or > to select the temperature.

4. Press  to accept the setting.

P2, Event 2-4:

Repeat the Event 1 procedure for programming Event 2-4.

---|---

The thermostat will continue the 4-event program based on the present time and day.

To set and change the room temperature temporarily:

1. Press < or > at any time to change the desired tem-perature value. SET is shown in the display.
2. When releasing the < or >, the display returns to showing the actual temperature. This temperature change is only temporary and will be maintained only until the next programmed setting!

A default program provides timer control if the customer does not create own programs:

Changing of desired temperature – press < or >. SET is showed in the display. Adjustment is changed in steps of 0.5°C When releasing < or > again the display returns to normal mode and shows actual temperature. It will be possible to set the maximum floor temperature up to 45°C. It would also be possible to use only one temperature sensor. However, this option is not recommendable as this cause an increased risk of overheating of the floor. Extending maximum floor temperature and Setting into room only mode – See point 4.9 and 4.10.

IMPORTANT: When the thermostat is used to control a floor heating element in connection with a wooden floor or similar material, always use a floor sensor and never set the maximum floor temperature to more than 35 ° C.
